There have been some long standing expectations for Revel to eventually rework the Ultima2 series, and they had displayed he very first change to them since their introduction. Two new finishes, one called Aston Martin Silver and the other rich chocolate that I hadn't seen named. In addition to the new finishes, pricing was updated to $20,000 and $26,000 respectively. Not that these are major changes, and I honestly hope they do have something interesting up their sleeve, but I don't feel they have something impending to replace them. Would be happy to learn otherwise.
When Revel released the Ultima2, it was benchmark product and over ten years later still holds its own very well. I personally do agree they would certainly be well worth a listen, with the only mention of note is the speaker will lean on its partnering amp a little.
